Last year NASA’s chief scientist pretty much confirmed that the government space agency believes that alien life exists. While Ellen Stofan said that she thinks humanity will confirm “we are not alone” by the year 2025, others in the alien hunting community took this as a hint that NASA is already communicating with intelligent aliens. She actually said; "I think we're going to have strong indications of life beyond Earth within a decade, and I think we're going to have definitive evidence within 20 to 30 years."
